Hello Ricardo:)

I'll leave you some little details but good lab in general! Gradually the things are getting rhythm:) Congratulations 💥

• Calculate the square root of the first 100 numbers. Use sqrt as the name of the list.

I like the way you have used numpy! We will see it today:)

• Find all of the numbers from 1-1000 that are divisible by 7. Use divisible_by_seven as the name of the list.

divisible_by_seven2=[i for i in range(1,1001)  if i%7 == 0]
print(divisible_by_seven2)

It asks you for the numbers divisible by 7 from 1-1000, in your range you specify range(0, 1001) so you include also the 0🫠 little confusão hehe (but your code is OK!!)

• Remove all of the vowels in a string. Hint: make a list of the non-vowels. Use non_vowels as the name of the list.

vowels = "aeiouAEIOU"
non_vowels = [i for i in teststring if i.lower() not in vowels and i != ' ']
print(non_vowels)

Here is a more efficient and shorter way to achieve the same result!!!

• Handle the exception thrown by the code below by using try and except blocks. (division by 0)

try:
    z = x/y
except ZeroDivisionError:
    print(f"I cannot divide a number by {y}")

Your answer is correct and it works! I just wanted to let you know that the ZeroDivisionError exception is more specific to this particular error.

• Handle the exception thrown by the code below by using try and except blocks. (index)

Idem that the previous exersice but with 'IndexError'.

I leave you the BONUS as well:

• Bonus 1

 def square_cal():
    x = input("Insert an integer to square")
    integer=False
    while integer == False:
        try:
            x= int(x)
            integer == True
            return x**2
        except ValueError as error:
            x = input(f"{error}, please insert an valid integer to square")
square_cal()

• Bonus 2

 results = list(set([num for div in range(2,10) for num in range(1,1001) if num%div == 0]))
print(results)

• Bonus 3

 class NumSectionsError(Exception):
    pass
while True:
    try:
        Total_Marks = int(input("Enter Total Marks Scored: "))
        break
    except ValueError as error:
        print(error)
while True:
    try:
        Num_of_Sections = int(input("Enter Num of Sections: "))
        if Num_of_Sections > 2:
            raise NumSectionsError
        else:
            break
    except ValueError as error:
        print(error)
    except NumSectionsError:
        print("The number of sections can't be bigger than 2") 

Let's go for the next laaaaaaaab! 💥
